										integral lim x=0 to infinity x^2/x^2sin^2xe^2cos^2x
=integral lim x=0 to infinity 1/sin^2xe^2cos^2x
=1/e^2integral lim x=0 to infinity4/(2sinxcosx)^2
=4/e^2integral lim x=0 to infinity dx/sin^2(2x)
=4/e^2 integral lim x=0 to infinity cosec^2(2x) dx
=4/e^2 [(-cot2x)/2] x=0 to infinity
=2/e^2[-cot infinity+ cot0]
=infinite

∫1+tanxtan(x+a)dx
 
 
We know that, tan(c-b) = (tan c – tan b)/(1+tan c * tan b), So, (1+tan c * tan b) = (tan c – tan b) / tan (c-b), Put c= x+a, b=x, (1+tanx * tan(x+a)) = (tan(x+a) – tan x) / tan(x+a-x)...

How to prove 1 + Cos4x/2 = Cos 2 2x .
 
 
we know that cos2x= 2cos 2 x -1 replace x by 2x then cos4x=2cos 2 2x -1 so,(1+2cos 2 2x -1)/2 =(2cos 2 2x)/2 =cos 2 2x

1+cos4x/2= (1+2cos 2 2x -1)/2 because cos2x=2cos 2 x -1 so =2cos 2 2x/2 = cos 2 2x. Hence the proof
